Other objects will be in part obvious and in part hereinafter pointedout.

The invention accordingly consists in the features of construction,combination of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the claims hereuntoappended.

the pintle E of which has mounted thereon an arm 10 which has connectionwith the lock for holding the door in adjusted open position,hereinafter fully described.

Upon the head B of the door frame A is mounted a segment 11 formed inits lower edge with spaced notches 12 providing therebetween rack teeth13, while fixed to the door C is a lock housing 14 having arrangedtherein a sliding bolt 15 which is adapted to engage in any one of thenotches 12 in the segment 11 for holding the door when opened inadjusted position at an angle to the door frame. The bolt 15 is formedwith a reduced end 16 which extends without the housing 1a andterminates in an eye 17 in which is connected the upper hook end 18 of arod 19, the opposite hook end 20 of which is engaged in the free end ofthe lever 10 so that on the turning of the pintleE in one direction therod 19 will pull upon the sllding bolt 15 to retract the same within thehousing 14:, and on the turning of the pintle E in this direction thedoor will be unlatched for the opening thereof, the pintle E beingprovided with the usual hand knob 21 to permit the turning thereof.

Surrounding the reduced end 16 of the sliding bolt 15 is a coiledexpansion spring 22 which serves to act upon the bolt for throwing thesame into locking engagement in any of the notches 12 in the rail 11 forthe locking of the door C in open position at any angle relative to thedoor frame.

Mounted to straddle the rail 11 is a loop or yoke 23 which is fixed tothe uppermost end of the housing 14;, and this yoke or loop follows therail during the opening movement of the door C.

Mounted on the housing is a pivoted arm 24 formed with a lug 25projected inwardly through a slot 26 in the said housing to engage in aU-shaped slot 27 formed in the sliding bolt 15 so that the bolt can belocked in extended or retracted position on the swinging of the arm 24:upon its pivot. The.

arm 2%, when swung to the right, permits the lug 25 to engage theperpendicular portion of the slot 26, and on the swinging of the arm tothe left the lug enters either of the horizontal stretches of the slotfor the looking of the said bolt in extended or retracted positions.When the bolt is extended it will engage in any of the notches 12 onopposite sides of the teeth 14 on the rail 11 and thereby hold the doorin locked open positeriorly to the housing for swinging movement, a pinmounted 1n the arm and passed through the housing for engagement in the1 slot in the bolt to traverse the same for looking the said bolt inextended or retracted positions.

In testimony whereof I atlix my signature in presence of tWo Witnesses.
